#include "stdafx.h"

#include <string>

using namespace std;

int main()

{

    string tol,result;

    while(getline(cin,tol)) {

        unsigned i=;

        if(tol=="START") continue;

        else if(tol=="END") cout<<result<<endl;

        else if(tol=="ENDOFINPUT") break;

        else {

            while(i<tol.size()) {

                if(tol[i]< &&tol[i]>=)//A-E

                    tol[i]= tol[i]+ ;

                else if(tol[i]>=&&tol[i]<=)//F-Z

                    tol[i]= tol[i]- ;

                i++;

            }

            result=tol;

        }

    }

    return ;

}

　　可用map映射字母一一对应来替换,此处我就直接替换了,只是不方便扩展
